Miscellaneous Changes

• You can now use the "F" shortcut to focus on light filters in the Hydra Viewer (Katana 3)
  
• Improved drawing lights and light filters with transparency in the Hydra Viewer (Katana 3)
  
• Added the option to use "objectdistance" dicing in RfK, see the RenderMan 22.3 release notes for more details
• You can now edit the "tint" and "intensityMult" parameters of PxrPortalLight in the corresponding "Color" and "Int" columns in GafferThree.  You can also edit the "skyTint" parameter of PxrEnvDayLight in the "Color" column
• There is a new option in PrmanGlobalStatements - "plugin.deferInstanceSources" which tells RfK not to traverse and build instance sources that aren't instanced
• The global plugin option "recover" is now correctly emitted to the prman command line
• Cameras now inherit relevant attributes from /root. The prmanCameraStatements, material, and geometry attributes from /root are merged with those on camera locations.  Additionally, cameras that are children of cameras will inherit the attributes from their parent cameras.  To get the old behavior back, you can set this attribute at /root: info.__prmanOriginalCameraBehavior.
• Cameras now use the fov from the geometry.fov attribute by default.  You can switch to use the projection shader's fov parameter by setting the prmanCameraStatements.useGeometryFov attribute to 0.  To enable fov motion blur using the geometry.fov attribute's time samples, enable prmanCameraStatements.fovMotionBlur.  These settings are available on the PrmanCameraSettings node.  To get the old behavior back, you can set this attribute at /root: info.__prmanOriginalCameraBehavior
• Removed the extra blank line in the Render Log after each loaded shader library
• The page, label, and help hints are now available from the RendererObjectInfo for c++ plugins
• The default number of parallel traversal threads has been changed from 0 ("automatic") to 4. In many cases this will result in parallel traversal performance
  improvement
• In the Hydra Viewer, (Katana 3) don't display parent locations that are not included in the Viewer Visibility Working Set
• The Barn Edge scale manipulator handles are now hidden if the "edge" value is zero
  

Fixes

• The RfK preset browser would incorrectly accept network materials that were not above the view node in the nodegraph
• The "visible" attribute will now work with all types of instancing and with light locations
• Attributes set under prmanStatements.primAttributes are now correctly applied to renderer procedural locations
